SPECIFICATION forming part of Letters Patent No. 632,929, dated September 12, 1899.

Application tiled June 2,1899. Serial No. 719,122. (No model.)

To all wiz/07u t may concern:

Be it known that I, BnNHARDUs MAGNUSEN To'rDAHL, a citizen or' theUnited States, residing at St. Olaf, in the county of Otter Tail and State of Minnesota, have invented a new and useful \Vindmill-Regulator, of which the following is a specification.

'lhc invention relates to improvements in wind mill-regulators.

The object ofthe present invention is to improve the construction of windmill-regulators and to provide a simple, inexpensive, and eilicicnt device adapted to be mounted upon a tank or reservoir and capable when the water within the same reaches the desired height ot' automatically throwing the wind mill out of operation.

A further object of the invention is to provide a device of this character adapted to be connected with any ordinary windmill andV capable of being readily adjusted to take up any slack of the connections.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation partly in section, showing a windmill-regulator constructed in accordance with this invention and mounted on a tank, the parts being set and the windmill beingin operation. Fig. 2 is a similar view illustrating the position of the parts when the device is tripped. Fig. 3 is a detail perspective View of the bell-crank arm of the shaft. Fig. 4 is a similar view of the trigger. Figs. 5 and 6 are detail sectional views illustrating the manner of mounting the vertical tube.

Like numerals of reference designate corresponding parts in all the iigures of the dra-wings.

1 designates a standard or support provided at its lower end with a base or attachment plate 2 and designed to be secured upon a tank, as clearly illustrated in Fig. 1 of the accompanying drawings, and the upper portion of the standard is curved over the base and is provided with a perforation, in which is arranged a vertical tube 4. The lower end of the tube 4 is provided with a flange 5 and is stepped in a perforation of the base, and the upper end of the tube is secured in the per- 4throw the windmill out of the Wind.

foration of the standard bya set-screw 6. Dis; posed on the tube 4 is a coiled spring 7, which engages a sliding collar 8, and thelatteris connected by links with a bell-crank arm or dog fl of a shaft 10 and is arranged within a slot 1l of the upper portion of the standard. The bellcrank arm or dog is connected with the sliding collar by means of a pair of links 12, and the shaft 10 carries an arm 13, which is rigid with the shaft and the bell-crank arm or dog, the whole forming a lever for drawing a windmill out of the wind.

The spring is adapted to be compressed by rotating the shaft, which is locked to retain the spring in its compressed position by a trigger which engages the upper projecting portion 14. The trigger 15 is adapted to be released by the rising of the water within the tank, whereby the spring is permitted to expand and throw the windmill out of the wind. The trigger is mounted Within the upper portion of the slot of thestandard on a transverse pin 16, and it is provided with a notch 17, forming a shoulder, which is adapted to en gage the bell-crank dog or arm of the shaft.

The arm 13 of the shaft is connected by a wire 1S with a bell-crank lever 19,t`ulcrumed at its angle on the tower 2O of a windmill andhaving one of its arms connected with the mechanism for throwing the windmill out ofthe wind. The straight arm 13 of the shaft is elevated to compress the spring and set the windmillregulator for operation, and when the device is tripped the arm 13 is swung downward, whereby the bell-crank lever is operated to The arms of the bell-crank lever and the arm 13 of the shaft are designed to be provided with perforations to permit the connections to be adjusted to take up any slack of the parts.

lVithin the vertical tube 4 is arranged a rod 21, forming a guide fora float 22, located within the tank and adapted to be moved upward by the water rising within the same. The rod or stem of the iioat projects above the standard and carries a horizontal tripping device 23, adjustably secured to it and provided with an opening 24: for the reception of the trigger, which is arranged at an angle to the rod or stem when the parts are set, whereby the said trigger is adapted to be drawn inward by the rising of the iioat to trip the device. The tripping device is provided at IOO its inner end with a socket or head and is secured to the rod or stem by a set-screw 25. The tension of the spring is adjusted by a lower collar 26, arranged on the vertical tube and forming a bearing for the lower end of y The invention has the following advantages: The windmill-regulator, which is simple and comparatively inexpensive in construction, is strong and durable and adapted to be readily applied to a windmill and a tank, and it is capable of being set so that the windmill will be thrown out of operation when the water in the tank rises toagiven height. The spring, which is compressed when the device is set, may have its tension readily regulated, and the tripping device is adjustably mounted on the rod or stem of the float, whereby the device may be tripped when the water is at any desired height. The trigger which holds the lever in its set position is disposed at an angle to the rod or stem of the iioat and is pivotally mounted, so that only a very small ioat is necessary to operate the windmill-regulator.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

l. A windmill-regulator comprising a support mounted on a tank or reservoir, a lever fulcrumed on the support, means for connecting the lever with the operating mechanism of a windmill, a spring arranged to be compressed by the lever when the device is set and adapted when the device is tripped to draw the windmill out of the Wind, a trigger for setting the'lever, and afloat having a tripping device arranged to disengage the trigger from the lever, substantially as described;
